On April 25, 2006, an approximately six-mile-long oil slick in Delaware Bay was reported by a tugboat crewman. A few days later, a sample of the released oil was matched to an oil sample taken from a container ship, the Bermuda Islander. The total volume of oil released and the cause of the release are unknown. The spill impacted approximately 40 miles of the western shoreline (Delaware side) and less than one mile of the eastern shoreline (New Jersey side) of Delaware Bay.
Atlantic horseshoe crabs (Limulus polyphemus) are shown spawning on the shoreline at Mispillion Harbor, Delaware, in early June 2008. Restoration of this spawning beach is one of the preferred natural resource restoration alternatives in the Draft Restoration Plan., Credit: Gregory Breese, USFWS
